Perimeter protection
Thermal and radar cameras, fence and buried sensors, fibre distributed acoustic sensing and tripwire analytics for plants, solar farms and protected sites.
Home / Security and fibre
CCTV, security systems and fibre optics
Perimeter protection, video surveillance, access control and the fibre networks behind them. Designed, supplied, installed and maintained by DIS on Bosch, Dahua and Hikvision.
Service provider
One contractor from camera survey to maintenance contract
We work as the security systems service provider for plants, utilities, solar farms and remote sites: we design the coverage, supply the equipment, install and integrate it with SCADA, and keep it running.
For oil and gas sites we supply explosion-proof cameras and enclosures certified for the hazardous area, and we keep security networks segmented from control networks to IEC 62443.
Solutions
Security solutions by scenario
Combined to suit the site: a remote well field needs different coverage, storage and power from a refinery gate.
Video surveillance
IP fixed, dome and PTZ cameras, ANPR, and explosion-proof cameras certified for hazardous areas in oil and gas facilities.
Control rooms and VMS
Video management, NVR and server storage sized to retention policy, video walls and operator consoles, integrated with SCADA alarms.
Access control and intrusion
Card and biometric readers, turnstiles and barriers, intrusion alarm panels and gate intercoms, linked to the video system.
AI video analytics
Intrusion, loitering and PPE detection, smoke and fire detection, people counting and vehicle recognition at the edge or on servers.
Network and transmission
Industrial switches, PoE, ring topologies, point-to-point wireless links and the fibre backbone that carries video and SCADA.
Fibre optics
Fibre backbones, spliced and tested by our own teams
Single-mode and multimode networks for SCADA, substations, IEC 61850 and video, with every link tested and documented before handover.
OTDR trace, illustrative
Design
- Route survey and fibre route design
- Single-mode and multimode selection
- Ring and redundant topologies
- Loss budgets for every link
Installation
- Armoured and duct cables, pulling and blowing
- ODF, patch panels and splice closures
- Fusion splicing with recorded splice loss

Testing and handover
- OTDR traces in both directions
- Light source and power meter tests
- Labelling to the client standard
- As-built route drawings and test reports
How we deliver
Survey, supply, install, commission, maintain
The same team stays with the system, so the people who installed a camera are the people who fix it.
Survey and design
Site survey, camera coverage and lens studies, 3D site models, network and storage sizing.
Supply
Bosch, Dahua and Hikvision equipment, hazardous-area cameras, poles, cabinets and power.
Installation and integration
Poles, cabling and fibre, camera set-up, VMS configuration and SCADA alarm links.
Commissioning
Picture-quality acceptance, analytics tuning, cybersecurity hardening and operator training.
Maintenance contracts
Preventive visits, health monitoring of every camera and recorder, agreed response times.
